Technical Field

The invention relates to a multi-way valve, in particular a cooling water valve of a motor vehicle or a cooling water valve for a motor vehicle, and to a method for actuating a multi-way valve.

Disclosure of Invention

The object of the invention is to improve a multi-way valve.

This object is achieved by a multi-way valve having the features of claim 1. Claims 11 and 12 protect a motor vehicle having at least one multi-way valve described here, and a method for operating a multi-way valve described here. Advantageous embodiments of the invention are the subject matter of the dependent claims.

According to one embodiment of the invention, the multi-way valve has a one-piece or multi-piece housing with two or more, preferably at least or exactly three or four connections, and a one-piece or multi-piece control element which selectively blocks one or more of these connections or is provided, in particular arranged or used, for this purpose.

In particular, for this purpose, according to one embodiment of the invention, the control element is arranged (in one embodiment supported) rotatably, in particular about the axis of rotation and/or rotatably in different positions, in a recess of the housing.

The invention can be used particularly advantageously in such a multi-way valve.

According to one embodiment of the invention, the outer contour of the control element, in one embodiment of its convex or outwardly arched (radial) circumferential surface, has a compression section which, in at least one first position of the control element, in one embodiment at least partially elastically, compresses a first seal arranged on a first one of the joints, or is provided or arranged or used for this purpose. In a development, the control element blocks the first connection in the first position, or is provided or arranged in such a way or for this purpose or is used for this purpose.

This blockage can thus be improved in one embodiment.

According to one embodiment of the invention, the outer contour of the control element has a pressure-reducing section, which has a smaller radius than the compression section, and in at least one further position of the control element, in which the control element does not block the first connection in one embodiment, is located opposite or faces the first seal, so that the control element compresses the first seal less in the further position than in the first position, or is provided or arranged in such a way or for this use or is used for this use.

Thus, in one embodiment, the first seal is unloaded/depressurized when not needed. In one embodiment, the service life, the reliability and/or the sealing effect of the seal can thereby be increased and/or the operating forces for adjusting the multi-way valve can be reduced.

In one embodiment, the radius of the compression section or the (smaller) radius of the decompression section is the maximum, minimum or average distance or spacing between the respective section or outer contour and the axis of rotation of the control element in at least one cross section, in one embodiment in at least one cross section perpendicular to the axis of rotation, which cross section in one embodiment also intersects the respective seal.

In one embodiment, the pressure-relief section supports the first seal on the housing in the further position of the control element, or is provided or arranged in such a way or for this purpose or is used for this purpose.

In one embodiment, the risk of the first seal undesirably falling out of the receptacle can thereby be reduced, and the function and/or reliability of the multi-way valve can thereby be improved in one embodiment.

Additionally or alternatively, in one embodiment, the pressure-reducing section does not compress the first seal in said further position, or is provided or arranged in such a way or for this purpose.

Thus, in one embodiment, the first seal is particularly substantially unloaded. In one embodiment, the service life, the reliability and/or the sealing effect of the seal can thereby be further increased and/or the operating forces for adjusting the multi-way valve can be further reduced.

In one embodiment, the compression section compresses a second seal arranged on a second of said joints in at least one second position of the control element, or is provided or arranged in such a way or for this purpose or is used for this purpose. In a development, the control element blocks the second connection in the second position, or is arranged or arranged in such a way or for this purpose or is used for this purpose.

This blockage can thus be improved in one embodiment.

In one embodiment, the control element compresses the second seal more in this second position than in at least one other position of the control element, and in one embodiment compresses the second seal more strongly than in the first position of the control element, or is provided or arranged in such a way or for this purpose or is used for this purpose. In a further development, the control element does not block the second connection in the further position, or is provided or arranged in such a way or for this purpose or is used for this purpose. Additionally or alternatively, in one embodiment, in particular for this purpose, the pressure-relief section is located opposite the second seal in the further position.

Thus, in one embodiment, the second seal is unloaded/depressurized when not needed. In one embodiment, the service life, the reliability and/or the sealing effect of the seal can thereby be increased and/or the operating forces for adjusting the multi-way valve can be reduced.

In one embodiment, the pressure-relief section supports the second seal on the housing in the further position of the control element, i.e. in one embodiment in the first position, or is provided or arranged in such a way or for this purpose or is used for this purpose.

In one embodiment, the risk of the second seal undesirably falling out of the receptacle can thereby be reduced, and the function and/or reliability of the multi-way valve can thereby be improved in one embodiment.

Additionally or alternatively, in one embodiment, the pressure reducing section does not compress the second seal in said other position, or is provided or arranged in such a way or for this purpose.

Thus, in one embodiment, the second seal is particularly substantially unloaded. In one embodiment, the service life, the reliability and/or the sealing effect of the seal can thereby be further increased and/or the operating forces for adjusting the multi-way valve can be further reduced.

In particular, the control element or its outer contour can also be designed in such a way that the compression section in the first position compresses the first seal, in particular at least partially, and in the second position compresses the second seal, in particular at least partially, and in contrast to this, the decompression section in the first position unloads or compresses the second seal less, if appropriate not at all, and in the second position unloads or compresses the first seal less, if appropriate not at all.

In one embodiment, the relief section is arranged in front of the first joint instead of the compression section when the control element is adjusted from the first position into the second position, and instead of the decompression section, a compression section is arranged in front of the second joint, and thereby the compression of the first seal by the control element is preferably continuously reduced, or preferably continuously and/or conversely, the compression of the second seal by the control element, and conversely, when the control element is adjusted from the second position into the first position, the compression section is arranged in front of the first joint instead of the decompression section, and instead of a compression section, a decompression section is arranged in front of the second connection, and the compression of the second seal by the control element is thereby preferably continuously reduced, or to continuously and/or conversely enhance the compression of the first seal by the control element.

Additionally or alternatively, in one embodiment, in particular in the circumferential direction or rotational direction about the rotational axis (viewed), at least one, in one embodiment exactly one, further (third) connection is arranged between the first connection and the second connection, which in one embodiment is (fluidly) connected or communicates with the second connection in the first position of the control element and/or with the first connection in the second position of the control element.

The invention can be used particularly advantageously for such a joint arrangement and/or a (more) compact multi-way valve can be realized.

In one embodiment, the control element is in at least one third position of the control element, in which it does not block the first and second connections in one embodiment, the first seal is compressed less than in the first position and/or the second seal is compressed less than in the second position, the seals are compressed only locally and/or less strongly (respectively) in one embodiment, or is provided or arranged in such a way or for this use or is used for this use.

In one embodiment, the respective seal is thus particularly largely relieved. In one embodiment, the service life, the reliability and/or the sealing effect of the seal can thereby be further increased and/or the operating forces for adjusting the multi-way valve can be further reduced.

Additionally or alternatively, in one embodiment the control element supports the first seal and/or the second seal on the housing in at least one or a third position (in which position the control element does not obstruct the first and second joints according to one embodiment) or is provided or arranged in such a way or for this use or used for this use.

In one embodiment, the risk of an undesired removal of the respective seal from the receptacle can thereby be further reduced, and the function and/or reliability of the multi-way valve can thereby be further improved in one embodiment.

Additionally or alternatively, in one embodiment, the control element does not compress the first seal and/or the second seal in this third position, or is provided or arranged in such a way or for this purpose.

In one embodiment, the respective seal is thereby unloaded particularly greatly. In one embodiment, the service life, the reliability and/or the sealing effect of the seal can thereby be further increased and/or the operating forces for adjusting the multi-way valve can be further reduced.

In an alternative embodiment, the control element (also) compresses the first seal and/or the second seal in the third position, or is provided or arranged in such a way or for this purpose.

Thus, in one embodiment, the adjustment of the multi-way valve and/or the increased compression of the first or second seal is improved upon adjustment into the first or second position.

In one embodiment, the control element connects at least two of the joints in at least one position, in particular in the first, second and/or third position (respectively), via a through-channel of the control element, which in one embodiment has at least one, in particular lateral or radial, groove ("slotted through-channel"), and blocks at least one of the at least two joints in at least one further position of the control element, in one refinement the control element connects at least three of the joints in at least one position via the through-channel, or is provided or arranged in such a way or for this use or is used for this purpose.

In one refinement:

-the control element connects a first of said joints and at least one further (third) joint via a through-going channel in the second position and blocks the first joint in the first position; and/or

The control element connects the second of the connections and at least one, in particular the further (third) connection, via the through-channel in the first position and blocks the second connection in the second position; and/or

The control element connects the first and second of the joints and at least one, in particular the further (third) joint, via a through-channel in the third position, or is provided or arranged in such a way or for this purpose or is used for this purpose.

In such a connection device, the invention can be used particularly advantageously and/or a (more) compact multi-way valve can be realized.

In one embodiment, the groove is arranged completely or partially in the pressure-reducing section.

In one embodiment, the risk of stress and/or damage to the first and/or second seal by the groove or its (outer) edge can thereby be advantageously reduced.

In one embodiment, the compression section and the decompression section transition into one another continuously, in particular without interruption/step, in one embodiment the radius of the outer contour of the control element decreases continuously, in one embodiment monotonically, from the compression section to the decompression section.

In one embodiment, local stresses on the respective seal can thereby be reduced or avoided, and the service life, reliability and/or sealing effect of the seal can thereby be further increased.

In one embodiment, the first seal, which is designed in a multi-part and/or annular manner, may in particular have an elastic ring which is arranged in one embodiment on one support ring or between two support rings, wherein in one embodiment the support ring or one of the support rings is supported on the housing or the first joint and/or the support ring or one of the support rings is supported on the control element. In addition or alternatively, in one embodiment, the second seal is configured in multiple parts and/or in a ring shape, which may in particular have an elastic ring, which in one embodiment is arranged on one support ring or between two support rings, wherein in one embodiment the support ring or one of the support rings is supported on the housing or the second joint and/or the support ring or one of the support rings is supported on the control element.

The invention can be used particularly advantageously in such seals.

The invention can be used particularly advantageously in motor vehicles and/or as a cooling water (control or regulating) valve, in particular on the basis of thermal, flow-technical and/or mechanical boundary conditions and/or installation situations.

According to one embodiment of the invention, for actuating the multi-way valve described here, the control element is adjusted between a first position, in which the compression section compresses the first seal and the control element blocks the first port in one embodiment, and one or more further positions, in which the decompression section is located opposite the first seal, so that the control element compresses the first seal less than in the first position, wherein in one embodiment the control element does not block the first port in the further positions.

Detailed Description

Fig. 1 shows a multi-way valve according to an embodiment of the invention in a longitudinal section, comprising an axis of rotation R.

The multi-way valve has a multi-part housing with a housing body 10 and a housing cover 14, which is omitted from the top view in fig. 2.

The housing has a first connector 11, a second connector 12 and a third connector 13.

A control element 20 for selectively blocking the first or second coupling 11, 12 is rotatably supported about the axis of rotation D in the recess 15 of the housing.

The outer contour or the circumferential surface of the control element 20 has a compression section 21 which, in a first position (see fig. 3(a)), in which the control element 20 blocks the first connection 11, compresses the multi-part, annular first seal 1 arranged on the first connection 11.

The outer contour of the control element 20 has a pressure relief section 22, which, in a second position (see fig. 3(c)) of the control element 20, in which the control element does not block the first connection 11, is located opposite the first seal 1 and has a smaller radius than the compression section 21, so that the control element 20 compresses the first seal 1 less in the second position than in the first position, wherein the pressure relief section 22 continues to support the first seal 1 on the housing in the second position of the control element.

In a second position of the control element (see fig. 3(c)) in which the control element 20 blocks the second connection 12, the compression section 21 compresses the multi-part, annular second seal 2 arranged on the second connection 12.

In this case, the control element 20 compresses the second seal 2 more strongly in the second position (see fig. 3(c)) by means of its compression section 21 than in the first position (see fig. 3(a)) by means of its decompression section 22, but in the first position the second seal 2 is also supported on the housing by means of its decompression section 22.

In a third position of the control element 20 (see fig. 3(b)) in which it does not block the first and second connections 11, 12, the control element 20 supports the two seals 1, 2 on the housing.

The control element 20 connects the connections 12 and 13 via a passage opening with a lateral slot 23 in a first position (see fig. 3(a)) and blocks the second connection 12 in a second position of the control element (see fig. 3 (c)).

In the second position (see fig. 3(c)), the control element 20 connects the connections 11 and 13 via the passage opening with the lateral groove 23 and blocks the first connection 11 in the first position of the control element (see fig. 3 (a)).

In the third position (see fig. 3(b)), the control element 20 connects the connections 11, 12 and 13 via the passage openings with the lateral slots 23.

While exemplary embodiments have been illustrated in the foregoing description, it should be noted that a vast number of variations can be implemented. It should also be noted that the exemplary embodiments are only examples, and should not limit the scope, applicability, and configuration in any way. Rather, the foregoing description will provide those skilled in the art with a guidance for implementing at least one exemplary embodiment, in which various changes may be made, particularly in matters of function and arrangement of parts described without departing from the scope of protection afforded by such combination of claims and equivalent features.
